Longitudinal Correlation of Thyroid-Stimulating Immunoglobulin With Clinical Activity of Disease in Thyroid-Associated Orbitopathy

Abstract

It was found that changes in inflammatory phase of TAO, as measured by the TAOS score, statistically correlate with changes in measured TSI. An additional correlation was also found between the absolute score of TAO activity and measured level of TSI. These findings suggest that serial TSI measurements may be an adjunct in assessing clinical inflammatory activity of TAO and may help direct clinical decision making regarding treatment decisions in TAO.
